salt and ice containers or brine containers` connected with a source of refrigeration.

yThe objects of my invention are, first, to provide metallic tanks or containers, constructed to carry a quantity of broken ice and salt, or brine connected with a source of refrigeration, and having a plurality of vertical flanges extendinglaterally from the sides thereof, for the purpose of increasing the metallic surfaces of the containers or tanks exposed to the air to be cooled.

Second: To provide a means to convey salt water or brine from the inside of the tanks or containers to the outside and to the flanges attached thereto, for the purpose of removing frost and ice and to prevent the' accumulation of frost and ice upon'the outsideof the tanks and-the vertical flanges attached thereto.

Third: To provide a means for replenishing the salt and ice containers, or brine containers with a source of refrigeration, vor refrigerating material.

Fourth: To provide the containers with a means of drainage.

Fifth: To provide a means of increasing or diminishing the refrigerating surface exposed to the air content of the refrigerator.

Sixth: To provide a means of refrigeration adaptable to many, or all styles, designs or plans of refrigerators.

Figure l is a perspective elevation of my improvement. Fig. 2 is a perspective detail of a tank or container, and a coil of pipe from a source of refrigeration, the vertical laterally extending fianges attached to the sides of the containers, or tanks and the disposition of the material used to convey salt water or brine from the inside to the outside of the tanks and vertical flanges.

introduced into a tank I or a series Aof tanks forming a section when the same are toA be filled with brine instead of salt and ice, and connected with a eration. l

The letter J refers'to a frame or rack constructed to carry a plurality of tank sections, one above another and arranged so that the vertical airducts B will register to form a continuous flue.

The letter Krefers to the horizontal air spaces between the sections. y Y n The letter L refers to the arrows representing the course of the current of warm air to the refrigerating tanks.

The letter M refers to arrows representing the course of the currents of cooled air away from the tanks. i

The letters O and P represent the flow from a source of refrigeration. l

The letter R refers to the runs or slides on which the sections of tanks rest when source of refrigplaced in the rack or frame J. The maning been placed in the ice compartment of a refrigerator, the sections are placed on their respective slides and the door to the ice compartment closed. The ice and salt mixture produces a very low temperature at the tanks. rlhe warm air L is cooled and settles to the bottom oit the ice compartment. This action of the air produces a circulation of' air, which extends to all parts of a refrigerator connected with the ice compartment. The intense cold produced in the tanks l causes moisture to condense and form ice and frost on the outside of the tanks l and the vertical flanges C, the salt water formed by the ice and salt is conveyed to the outside surfaces ot l and the flanges C, and melts the ice and frost, also prevents it forming. When the tanks l,need

reicing, the water is drawn o by the drain cock, G', the top saltV and ice container, or tank, is withdrawn wholly or the greater part of the way from ,its place in the frame, or rack, J, and is filled vwith salt and ice, and replaced. Asy inany sections may be Vcharged with ice and salt as appears necessary and when a means of refrigeration, such as brine circulating` from an ice machine or other source of refrigeration, the coils 4are introduced into the tanks T, which are lled with brine which is reduced to a Very low temperature. rhe salt water conveying material D furnishes brine to the outside of the tanks. The frost is kept off andthe combination much more eflicient than the coil alone.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent of the United States is:

1. In a refrigerator a salt and .ice container, consisting or a plurality of rectangular shaped tanks, spaced apart from each other and connected at their ends, in such a manner as to make up a section having` ice and salt tanks alternately with vertical air spaces between them; vertical wings or ianges extending from the sides of the ice and salt containers, sheets of fibrous or textile material disposed on the inner and outer surfaces of the salt and ice Y containers, whereby salt water is conveyed from the nside to the outside of the containers, and thev vertical wings or lianges, for the purpose of preventing or removing frost and ice thereon.

2. The combination of a plurality of salt and ice tanks or containers spaced apart from each other, a plurality or" vertical air spaces formed by such spacing apart, a plurality of vertical wings or flanges Vextending' laterally from the sides or the containers into the vertical air spaces between them, sheets of fibrous or textile material, disposed on the inner and outer surfaces of the salt and ice containers, for the purpose ofconveying salt water to the outside of the containers, and to the flanges attached to the Joan VWALKER MociaoNE.`
